UTILIZATION OF THE LAGTIFEROUS JUICES OF CAOUTCHOUC,

AND BALATA.

Patented Jul 9, 1907.

Application filed December 20, 1905. fierial No. 292.660.

l all whom it may concern: I I

Be it known that I, Looms Mosissn, a citizen of the Republic of France, and a resident of Paris, France, have invented a new and useful Improved Process for the Direct Utilization of the Lactiferous Juices of Uaou-tchouc, Gutta-Percha, and Balata, which process is fully set forth in the following specification.

Hitherto caoutchoucs, gutta perchas and balatas have reached the market in the form of loaves, blocks, sheets or the like. They are then treated by known processes for the purpose of converting them int manufactured articles.

- My application for patent of even date relates to a process for the treatment of the lactiferous juices of caoutchouc, gutta percha and balata, permitting of transporting them in a liquid state, and the present invention has for its objects process permitting of the direct utilization of these lactiferous juices while still liquid, for the purpose of obtaining manufactured articles.

In the case of caoutchouc juices the treatment is as follows: The milk is poured .directly in layers or otherwise upon or into the molds. frames or the like of wood, iron canvas, earth or other appropriate substances and the milk thus molded is then coagulated by a chemical, mechanical or physical agent of any suitable kind, and in the case of caoutchouc milks or beech creosote. 2.50 gr., guaiacol .50 gr., alcohol 90 50.00 gr. lommercial sulfuric acid is added to this ample. On an average, 150 grams approximately of this solution sufficiently coagulate, and'render antiseptic one liter of the milk. This solution also acts on the milk or juice in a manner similar to a vulcanizing agent, and the resulting product has substantially the same properties that vulcanization would impart to the same, that is to say, it does not stick together when cut, it resists high or low temperatures without change, and it retains exactly and permanently the shape that has been giverrto it. Nevertheless in the case of caoutchouc juice, the proportion of sulfuric acid should vary according as the juice belongs to one of the following sorts: hevea, castilloa, landolphia. manihot or other euphorbiacese.

In a manner similar to that set forth with reference to articles made of india rubber, it is possible, [or all the applications of plastic gums (gutta percha) .and mixed gums (balata) such applications comprising, for example, proofing' fabrics, the manufacture. of belts,electric wires and cables and so forth to employ the milks or juices in the liquid state instead of using dry gums and to coagulatethem during their molding by a physical means such as heat or vaporation in mono, or mechanical means such as churning, centrifugal treatment, or chemical means such as alcohol or other appropriate substance.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I LUCIEN MORISSE.
